So at this point I have been told in so many words that HPT will not fix this problem. Is there any other input before I contact "the other" company?
Have you tuned ANN back on just for giggles to see how it runs?
yes... same stuff
Not true.
HPT has everything you need to get a good result.
All the PD blowers will do this, the whipple more so as it is bigger and more aggressive.
Its a matter of getting the ETC tables to synch with the airflow and TQ values.
The TB will oscillate when the ETC commands a power % but the resulting airflow/TQ calc then reads too high.
The TB will close, open, close, open at PT till this is sorted out.
I have done plenty of these Jeeps, so it can be done.
Problem can be either TQ or airflow related.
If it is not TQ, then the Airflow needs to be using smaller numbers....sometimes REALLY small to get it to work well.
Everyone pumps up the airflow numbers and limits but these only apply at WOT.
PT kinda follows the OE airflow model numbers so that is why it won't allow the TB to stay open.
Had a quick peep at you large range airflow settings I found adjusting this so it expected much higher airflow for a given pos reduced the TB flutter significantly the fact that my curve has a bulge in it in the area that was my target has not caused any real issues ..driving wise reduced the problem say 50 % or more still chasing it tho
